In April, Dame Valerie told the Herald on Sunday that becoming a mother was bigger than any gold medal.

"We couldn't be happier," she said. "I've always wanted to be a mum. This is bigger for me than any gold medal.

"Gabe and I kept it between us for a very long time. I kind of freaked out a little bit because when you find out you start reading loads of things - and your brain naturally registers all the bad stuff.

"For the first time I wasn't able to control everything in my life and Gabe and I just felt like taking our time in letting people know was the right thing to do.

"But to finally tell people, that's really fun. We can relax a bit and start enjoying it."
